My right hon. Friend the Prime Minister has made it clear at the Dispatch Box and in the country that she wishes to prioritise certainty for UK nationals living in the EU 27 and for EU nationals living here in the UK, but I have it on good authority that the EU negotiators want to prioritise the so-called divorce settlement. Will she make it clear to the people with whom she is negotiating that we will not countenance British and EU citizens being used as bargaining chips in such a way?
